At 22:00UTC  I ran the MICH and SRCL FF measurements (see /lsc/h1/scripts/feedforward/README.txt) after the IFO had been locked 4 hours. The MICH comparism plot showed that the MICHFF has degraded with cold OM2 74861, some of this may be as the IFO was still thermalizing.

Gabirele fit the SRCL measurements. At 23:33UTC I loaded Gabirele's new SRCLFF (in FM7). I fit and saved the new MICHFF in FM4 .

After we lost lock 74874, I turned on both of these at 00:45UTC, saved/loaded in ISC_LOCK and Austin accepted in sdf snap and observe.snap. MICH comapre plot is greatly improved, note that as we are ~ 10 minutes into the lock that there is more noise.
